					IT leaders and Cloud computing

There’s also the tiny little issue of data. IT leaders do not trust online vendors
with the company data, including everything from customer information to
legal documents to intellectual property and trade secrets. And, what about
compliance? If the data isn’t handled properly and is in violation of Sarbox or
HIPPA regulations, who’s responsible?

And, what happens when the Internet goes down and all of your workers are
stuck twiddling their thumbs because they can’t access the company’s most
important piece of software? That’s the other big game-breaker for IT leaders
when they look at cloud computing.

Reasons why IT leaders will embrace cloud computing:

4. Separation of data from apps

It is quite possible that in the next few years we will increasingly see the front
end of applications separated from the backend. The front end will be
delivered in the Web browser while the backend will be powered by highly-
scalable databases.

As WAN speeds rise to over 100 Mbps, bandwidth costs decrease, and WAN
acceleration technology drives much more efficient use of WAN pipes, the
application front-end and the backend database will be able to exist in
separate locations much more easily and effectively. In some cases, this
could even allow companies to host the data inside their own private data
centers and simply allow the front end apps running in the cloud to tunnel in
and connect to the data.

3. Offline access for online apps

The future of cloud computing applications is not session-sensitive Web
pages that deliver applications that are unavailable when there’s a hiccup in
Internet access or loses a user’s form data when a backhoe accidentally cuts
a fiber line.

Following the example of Google Gears (and in some cases using the code),
we’re going to see the next generation of serious Web applications develop an
offline component in addition to the standard online component. This offline
functionality stores the application locally and caches user data so that any
hiccups to a Web session or connectivity outages allow users to continue to
work uninterrupted. Then when Internet connectivity is restored, any work and
changes made offline are simply synced up with the online version of the
application.

2. Ubiquitous mobile Internet access

While offline functionality will be necessary for Web applications in the cloud
to go mainstream, there’s also going to be significant progress made over the


                                                                                 1
next five years in making Internet access virtually ubiquitous - or at least
available anywhere you can connect to a cell tower.

The spread of both WiMAX and LTE - competing 4G wireless standards - will
bring broadband Internet to remote locations and will introduce true mobile
broadband connectivity to cars, busses, and trains. This will help remove one
of the psychological barriers to cloud computing: the idea that you can only
use it when you’re sitting at a desk where you have a high-speed connection.
The arrival of more powerful and versatile smartphones and netbooks,
combined with ubiquitous mobile broadband, will open up new possibilities for
cloud computing that will surpass most of what’s currently available with
standard software clients — and do it at a lower cost.

   1. Moving CAPEX to OPEX

Speaking of costs, that brings us to the main reason why IT leaders will
eventually adopt cloud computing. Scaling servers up and down is very
expensive. Most IT departments typically buy as many servers as they’ll need
during the company’s estimated peak capacity. However, they don’t need all
that capacity most of the time so lots of servers sit idle.

With cloud computing (and it’s cousin, utility computing), the equation
changes. When a company needs more capacity during its peak season, it
simply pays for it on-demand. When business slows down and the company
needs less capacity, its bill goes down because it’s using fewer resources.
In financial terms, this allows a company to move much of its infrastructure
costs from being a capital expenditure (CAPEX) to an operating expenditure
(OPEX). CAPEX costs are often tightly controlled since they involve
depreciating assets. The advantage to OPEX is that you can typically dial it
down and dial it up much more quickly and carefully.

Some vendors providing Cloud computing services are:

Yahoo, Google, Microsoft, Amazon, Salesforce, Zoho
